there is a bug in GCC 4.3.0 that makes roottest/root/hist/operator/runsparse.C fail in the error calculation part. Funny enough it fails because TH3 messes up its errors (not THnSparse  :-) .

The problem stems from TH1::GetBinError():
   if (fSumw2.fN) return TMath::Sqrt(fSumw2.fArray[bin]);
does not get evaluated properly - it has _horribly_ wrong values, e.g.
  -5063: 0.42
  +5063: 0.648074
("-" is GCC 3.4.6, "+" is GCC 4.3.0)
after scaling a bin with a single entry by 0.42. So this is a real issue. It's possibly connected to the new math compiler intrinsics + pushing their results onto the stack.

Attached patch fixes this, by introducing a temporary.

      Double_t err2 = fSumw2.fArray[bin];
      return TMath::Sqrt(err2);

The patch also fixes THnSparse::Scale() - it was also scaling the entries.

-  added  tests for  the following  cases:
   * TBtree with std::for_each (Full iteration: from the Begin up to the End)
   * TBtree with std::find_if
   * TBtree with std::count_if
   * TOrdCollection with std::for_each (Full iteration: from the Begin
     up to the End)
   * TOrdCollection with std::find_if
   * TOrdCollection with std::count_if

often). Also avoid unexpected <string> inclusion.
